In a metallic-roughness PBR material, base color provides diffuse reflectance for non-metals and reflectance color for metals.

One map, two material roles
For dielectric surfaces it mainly represents diffuse color. For metallic surfaces it colors the reflected light, while the diffuse contribution is suppressed by the shader.
Check it without environment lighting
Use a channel-isolation view to spot unwanted highlights, cast shadows, seams, or inconsistent exposure in generated texture data.
